That's looking good FunkedOut.
I'd have reservations about adding your dye mixture to the Tru Oil if it has water mixed into it. TO & water won't get along.
And FWIW, I prefer to tint the wood and clear coat (Tru Oil, Poly etc) over that. I know others will tint their clear, but it's not how I do it.
If you're dead set on tinting the TO, maybe mix a batch of dye with just the alcohol. If you have any issue with the granules dissolving, strain it before adding to the TO. I'm sure the dye strength will still be just fine even if if not 100% dissolved.
If you don't think so, dip your bare finger into it and see how long it takes to get the stain off! (just KIDDING!!! - don't do it!!!)
